Search for potential amoebicides. Part V. N-substituted 2-nitro-4,5-dimethoxybenzamides and anils of 2-amino-3-methoxy and 2-amino-4,5-dimethoxybenzoic acids.

The authors in all have synthesised 28 new N-substituted 2-nitro, 4,5-dimethoxy-benzamides, and anils of 2-amino-3-methoxy and 2-amino-4,5-dimethoxybenzoic acids with a view to obtain potent amoebicides. Their work is based on the observation that a large number of dimethoxyphenyl substituted derivatives occupy an important place as antiamobic agents. Fourteen belonging to different series subjected to in vitro screening for amoebicidal activity against E. histolytica failed to show any significant activity.
